My 2020 Crosstrek is connected to the internet, but it only affects the infotainment system and remote start/stop/monitoring.

The rest of the car is completely offline, that includes Eyesight.

Fwiw there's enough intermingling between how the head unit (infotainment) operates wrt to the CAN bus that your car is essentially online.

Not parent, but thank you for sharing this, as is quite the read.

Sure thing! Cool read. It links into a very stellar 90 page report that kicked off much of the hacking cars research

That was a great read. Thanks for posting. I’ve been dabbling in reverse engineering embedded devices in my spare time. I find these kind of detailed reports on how someone solved a reverse engineering challenge to be fascinating.

Interesting page, and while what I said may be incorrect (it's not air-gapped or anything) - my intent was to say:

>The online subscription and cellular service connectivity is not directly interacting with the eyesight safety system.

The original article seemed to conflate them.

How do you know it "is completely offline, that includes Eyesight." I believe this is false. Also, the "repair issue" is concerned with (service bay) RF access to the proprietary sensors and memory attached to the vehicle's computer systems --not necessarily Internet connectivity to them.

Let me rephrase, I meant that those systems, while they may be exposed to the online systems, are not part of the subscription packages in any way - and don't use the internet to operate.
